Wireless chargers are now available for your smartphone and other devices. Many of the latest smartphones come with support for Qi wireless charging, but what exactly is that, and how do you use it?
Wireless charging means you won’t have to plug your phone into your charger anymore because it uses something invented by Nikola Tesla in the 1890s. (Yes, the same Tesla the electric cars are named after.) It’s called a Tesla coil, which transmits electricity without wires. If you have used an electric toothbrush, you may already grasp the concept.
To charge a smartphone, both the charger (such as the FosPower EnergyPad) and the phone have this type of coils inside, which are used to send and receive the charge. Developers of this technology explain how it works: “the charge passes between a transmitter and receiver coil placed closely together, usually only separated by the outer casing of the two devices (<7mm). The coils must be aligned to make the connection.”
Users and reviewers of wireless charging report that different smartphones have different “sweet spots,” so when first placing your phone on the wireless charger, you will notice when a good connection is made by your smartphone indicators.
